20090245946 | CUBIC BORON NITRIDE RADIUS END MILL - A cubic boron nitride radius end mill includes a sintered cubic boron nitride compact bonded to an end of a main body, and a cutting edge provided on the sintered cubic boron nitride compact. The wedge angle θt of the cutting edge is constant over the entire region of the cutting edge. A negative rake face is disposed on a face so as to extend over the entire region of the cutting edge, and the rake angle θn of the negative rake face satisfies the relationship −30°≦θn≦−50°. A joint cutting edge is disposed between an end cutting edge and a radius cutting edge in the cutting edge, the joint cutting edge having a concave angle γ0 which is smaller than the concave angle γ1 of the end cutting edge and which satisfies the relationship 0.5°≦γ0 ≦2°. | 10-01-2009 |
20140056658 | CUTTING TOOL WITH REMOVABLE HEAD - A cutting head having a tapered shaft portion, a helical flute, and a flat shoulder surface is fastened to a shank having a front end surface, a tapered hole, and a helical flute through a fastening attachment in the form of a helical coil. The fastening attachment has a sectional shape substantially analogous in shape to a space defined between the helical flutes. The fastening attachment is fitted in one of the helical flutes, and is threaded into the other of the helical flutes until the shoulder surface is brought into close contact with the front end surface of the shank, and the outer peripheral surface of the tapered shaft portion is brought into close contact with the inner surface of the tapered hole, thus fastening the cutting head to the shank. | 02-27-2014 |

20120298347 | AIR-CONDITIONING SYSTEM - There is provided an air-conditioning system in which at least one or some of a plurality of air-conditioning apparatuses are each controllable such that the indoor temperature is maintained between two set temperatures. All the plurality of air-conditioning apparatuses are switched to either one of heating operation and cooling operation on the basis of a temperature difference between the indoor temperature related to an air-conditioning apparatus that is in the first operation mode and a set target temperature and a temperature difference between the indoor temperature related to an air-conditioning apparatuses that is in the second operation mode and an upper temperature limit or a lower temperature limit. | 11-29-2012 |

20130187170 | METHOD FOR PRODUCING ALUMINUM NITRIDE CRYSTALS - Provided is a method for producing inexpensive and high-quality aluminum nitride crystals. Gas containing N atoms is introduced into a melt of a Ga—Al alloy, whereby aluminum nitride crystals are made to epitaxially grow on a seed crystal substrate in the melt of the Ga—Al alloy. A growth temperature of aluminum nitride crystals is set at not less than 1000 degrees C. and not more than 1500 degrees C., thereby allowing GaN to be decomposed into Ga metal and nitrogen gas. | 07-25-2013 |
20140184418 | AIR-CONDITIONING APPARATUS CONTROLLER AND AIR-CONDITIONING SYSTEM - An air-conditioning apparatus controller includes a light-emitting indicator that emits light in a plurality of colors, a main display that displays a setting screen for light-emitting indication by the light-emitting indicator, a touch panel through which an instruction related to settings displayed on the main display is input, a data processing unit of a controller that causes the main display to display the setting screen, and performs setting processing for assigning an indication color to an indication content to be provided by the light-emitting indicator, in accordance with the instruction transmitted from the touch panel, and a data storage unit that stores settings for the processing performed by the data processing unit. | 07-03-2014 |
20140217097 | WALL-MOUNT REMOTE CONTROLLER - The wall-mount remote controller includes a base fixable to a wall W and a cover releasably attached to the base, having a box shape with an open rear, and covering a front surface of the base. The cover includes a bottom surface having an insertion opening therethrough. In a lower front of the base, a spring hook is disposed. The spring hook includes a support extending frontward from the front surface of the base and a hook section extending downward from an end of the support and then extending rearward. A hook protrusion is disposed on a lower surface of an extending rear portion of the hook section. The hook protrusion is engageable with the insertion opening of the cover. The hook protrusion is disengageable from the insertion opening by upward bending of the hook section caused by pressing of the hook protrusion by the tool inserted through the insertion opening. | 08-07-2014 |
